A novel method for removing thin clouds from single satellite image is presented based on a cloud physical model. Given the unevenness of clouds, the cloud background is first estimated in the frequency domain and an adjustment function is used to suppress the areas with greater gray values and enhance the dark objects. An image, mainly influenced by transmission, is obtained by subtracting.

The goal was to train machine learning for automatic pattern recognition. MiniBooNE particle identification: This dataset is taken from the MiniBooNE experiment and is used to distinguish electron neutrinos (signal) from muon neutrinos (background).

    objective cloud type identification is possible, however, identification considering meteorological conditions and cloud patterns is difficult. On the contrary, cloud type identification by the human eye has the merit of being able to use meteorological conditions, cloud patterns, changes with time, and other comprehensive meteorological Size: 1MB.   Satellite data shows the global cloud region in visible and infrared ranges, but have an uncertainty in terms of weather events and large time interval between the two periods of measurements, which complicates the use of this information for very short range forecasts of weather by: 3.

Some mechanical procedures for automatically recognizing and classifying specific cloud patterns from satellite photography are described and several data reduction transformations that have detected and isolated certain Automatic pattern recognition of meteorological satellite cloud photography book in which cloud "streets" differ from randomly placed cloud elements.

Cloud Verification The first step of the verification process is to incrementally shiftthe initial cloud detection mask in the theoretical direction of the sun’s raysprojected in the image plane.

Thesun azimuth angle is easily known through knowledge of the time and position of the satellite when the image was acquired; which, in theFile Size: KB. Catalog of meteorological satellite data--ESSA 9 television cloud photography (v.1) [Unknown.] on *FREE* shipping on qualifying offers.

According to the characteristic that the gray value difference is quite obvious in different areas of the singles infrared cloud, this paper puts forward an algorithm of the eyed typhoon's center automatic positioning.

After pretreating the cloud image, we use the template to segment the airtight cloud wall area which has high gray value. In addition, the difference between gray values of the Cited by: 1.

This ortho-photo data is automatically generated by pattern recognition techni Author: LeeEun-Seok, JeongYoung-Sik, HassanHoucine, ShinByeong-Seok, ParkJong Hyuk. In this chapter, we will discuss some basic concepts about pattern and pattern recognition dealing with biometrics, as well as an illustrated general configuration of pattern recognition system.

Then, the techniques for image segmentation, including pixel classification, gradient-based segmentation, and edge detection, are reviewed in Section   The analysis of the typhoon is based on the manual pattern recognition of cloud patterns on meteorological satellite images by human experts, but this process may be unstable and unreliable, and we think could be improved by taking advantage of both the large collection of past observations and the state-of-the-art machine learning methods, among which kernel methods, Cited by: 4.

Automatic procedures usually take charge of low- and middle-level tasks, relieving human experts from part of the work. An example of a partly automated task is the tracking of meteorological structures, which is usually performed using techniques based on local correlation between pixel intensity by: 2.

Highlights A whole sky imaging system is used for the estimation of cloud classification. A multi color criterion is applied to detect broken and overcast clouds.

A simple method is presented for the detection of raindrops. The success of the classifier ranges between 78 and 95% for seven cloud by: The improved method has been tested using rapid-scan observations of Hurricane Eloise obtained by the GOES satellite on 22 September We performed cloud tracking using target selection (clustering) based either on visible or infrared data and tracked the targets using a pattern recognition by:   Katz, Y.H., “Pattern Recognition of Meteorological Satellite Cloud Photography” Proc.

The textural features considered in this study include both spatial and frequency features. The spatial features were mainly those based on spatial grey-level difference statistics and circular Moran Cited by: In the context of pattern recognition, a pattern is a vector of features describing an object.

This pattern is made up of measurements on a set of features, which can be thought of as the axes of a k-dimensional space, called the feature space. The aim of pattern recognition is to establish a relationship between a pattern and a class by: Y.H.
